How Much Gravel for a 14x36 Parking Pad?
How much gravel for a 14x36 parking pad is a quick volume problem. 504 square feet at 4 inches comes to 6.22 cubic yards. Gravel usually weighs about 1.3 to 1.5 tons per cubic yard, so plan on roughly 8.7 tons.
Volume and tonnage calculator →The math for a 14x36 parking pad
- Area: 14 × 36 = 504 sq ft.
- Depth in feet: 4 ÷ 12 = 0.333 ft.
- Cubic feet: 504 × 0.333 = 168.0 cu ft.
- Cubic yards: ÷ 27 = 6.22 yd³.
- Tons: × 1.4 = 8.7 tons.
The volume and tonnage calculator does this for any size.
Gravel needed by depth
| Depth | Cubic yards | Tons (approx.) | Tons +10% |
|---|---|---|---|
| 2 in | 3.11 | 4.4 | 4.8 |
| 3 in | 4.67 | 6.5 | 7.2 |
| 4 in | 6.22 | 8.7 | 9.6 |
| 6 in | 9.33 | 13.1 | 14.4 |
About gravel
Plain gravel is a loose term. Yards use it for rounded bank or river stone as well as for crushed rock, so ask whether the load is washed, crushed or a mix before you lock in a tonnage. Weight per yard is a planning number; the scale ticket at the yard is the real one.
Preparing the parking pad
Dig out organic soil, compact the subgrade and set an edge so the stone does not migrate onto the lawn. A pad that holds parked weight for long periods benefits from a dense base under the surface stone. Since the parking pad carries parked vehicles, a little extra depth is cheap insurance.
Ordering tips
- Round up. Compaction and uneven ground eat material. Adding about 10 percent is common.
- Delivery size. 9.6 tons fits in a single typical dump truck load; small loads may carry a delivery fee. See how many tons of gravel in a dump truck.
- Bulk vs bags. At this size bulk delivery is usually the practical choice.
- Where it drops. Have the truck dump as close to the parking pad as firm ground allows.
Where gravel fits
Works well for:
- Rural driveways and lanes where low upfront cost matters
- Drainage areas and around downspouts
- Temporary access while a site is under construction
Think twice for:
- Steep slopes, where loose stone washes downhill
- Spots plowed often, since plows push gravel into the lawn
- Areas next to doors, because stone tracks inside
Quick reference numbers
- Per inch over 100 sq ft: about 0.43 tons of gravel (0.31 cubic yards).
- Per inch over 1,000 sq ft: about 4.3 tons.
- Another size for comparison: a 12x24 area at 2 inches takes about 2.5 tons.
- Weight used here: about 1.4 tons per cubic yard.
Where estimates go wrong
- Mixing up cubic yards and tons. Yards are volume, tons are weight; convert with the product’s weight per yard.
- Ordering exactly the math. Uneven ground and spillage nearly always need a little more than the flat calculation.
- Skipping drainage. Water sitting under any surface softens the base and leads to ruts and potholes.
- Using inches as if they were feet. Depth has to be divided by 12 before you multiply; skipping that step inflates the order twelvefold.
